Ball socket for a ball joint

Abstract

A socket for a ball joint having a socket body with an opening and a hollow space, which comprises a concave inside peripheral surface that delimits the hollow space and extends around a longitudinal axis, and which is axially divided into two body halves which merge together in a transition zone, each of which comprises an inside peripheral surface half. A first body half comprises a first inside peripheral surface half which lies on a spherical surface and is closed, in the circumferential direction, and a second body half which comprises the socket opening, at least one slot extending axially and a second inside peripheral surface half which is closed in the circumferential direction, or closed apart from the slot. The second body half is designed such that the second inside peripheral surface half lies outside the spherical surface at least an axial distance away from the transition zone.

Description

[0001]This application is a National Stage completion of PCT / EP2017 / 077078 filed Oct. 24, 2017, which claims priority from German patent application serial no. 10 2016 224 045.5 filed Dec. 2, 2016.FIELD OF THE INVENTION[0002]The invention relates to a ball socket for a ball joint, having a ball socket body comprising a ball socket opening and a hollow space, which has a concave inside peripheral surface that delimits the hollow space and extends around a longitudinal axis orientated in an axial direction, and is divided along the longitudinal axis into two ball socket body halves arranged one behind the other, which merge into one another in a transition zone, each of which has an inside peripheral surface half of the inside peripheral surface that extends around the longitudinal axis, wherein a first one of the ball socket body halves contains a first one of the inside peripheral surface halves, which lies on a spherical surface and is closed in the circumferential direction, and a...

AI Technical Summary

Benefits of technology

The patent describes a new design for a ball socket used in joint housings. The design includes a slot that can be completely closed when the ball socket is fitted into the joint housing. The slot is formed by two projections in the injection-molding die. The design also includes a ball socket body with an outer circumferential surface that can deform when the ball socket is fitted into the joint housing, ensuring a secure fit. The technical effects of this design include improved sealing and better stability of the joint housing.

Problems solved by technology

In the course of wear tests, however, it has been found that under high loads, for example at surface pressures in excess of 130 MPa, the material of the ball socket flows into the area of the slot.

This is undesirable, since thereby the geometry of the ball socket and hence the preset bearing properties of the ball joint are changed.
